Beit known that I, FREDERICK BAUMGARTNER, ofthe city of Brooklyn, in the county of Kings, and State of- N ew York, have invented a new and useful Improvement in Windows vand Doors; and I do hereby declare that thevfollowng is a full, clear, and exact descriptionvof the same, reference being` had to the accompanying M-y invention is designed more particularly for application to the windows of coaches, to preventtheir constant disagreeable rattling, but it may heapplied to anykind of slidingvwndow or door forproducing weather-tight joints, as will behereinafter more fully explained.

The nature of my invention consists in a device composed oi' a combined frictienfwheelor roller and spring', vso constructed and applied to the windowthat the friction-roller will cause 'the sash -to press against the outside stop or parting-strip, accordingly as the window-frame is constructed, With force suiici'ent tofprevent the sash rattling, and also to form a weather-tight joint, in -which latter case weather-strips may be entirely dispensed with. In the accompanying drawing- Figure 1 is a front view of-my invention, showing the same appliedjto a coach-window.

Figure 2 is a vertical central section thereof, taken on the plane ofthe lline :v tig. 1.

Similarle'tters of refereuce'indicate. like parts in both ligures.

A designates a'lat spring,.which carries, in suitable bearings a, at soine point of" its length, say midway I thereof, a frictionwheel or roller, B. The spring A is provided at-it's ends' with slots b b, through which screws c, or other suitable fasteners, 'pass to secureit in planet C is a metallic cap lor box, in which' 'the'spring and roller are enclosed.' A slotor opening, d, is made in the frontwall of thecap C, suciently large to'admit'of the roller projeetingfthro'ugh it. This box is'rectangirlar in shape,in transverse 'section,and.iits upon 'the ,sash like metallic corner-pieces generally, its faceslbeing flush therewitl1,.and being secured by screws or otherwise. In the present instance, the saine screws which seeure'the front walLof the cap to the sash, pass also through the slots-b in the spring A, and secure' that also,

In applying the device to a window, I have found it well to out away enough of the sash directly underthc spring to allow the spring to sink 'loirenough todraw the roller suiicientlyzfar into the box C tc-present no `hindrance to the proper workirig of the sash at pointsl whereA it may t quite snugly between' the stop-strips,

but however far it may beforcedinto the box, its periphery will always bear against the inside or outside stopstrip, as the case maybe, and thus keep `the sashpressed against the stop-strip onfthel'opposite side of the sash. '.lhisn'n be better-understood by referring to iig. 2 of the drawing. The roller here 'bears against the inside stop E, and presses'the sash against the outside stops F F'.

In both figures the'uwindow-sash s lshown in a closed state. i To open'the window, it is only necessaryl to i press upon the knobj; (seeiig.1,) and,whle doing this, draw the sash slightly upward, which pressure on the knob throws the bottom strip ofthe sash out of the rabbet g, 'when' the sashl can be shoved' down.

It will be noticed, by referring to iig. "2, that the spring. and roller keep the sash pressed tightly'up against .the outside stop P", and hence it cannot rattle when the vehicle-is moving over uneven pavements, and, further than' that, a weather-tight'joint is produced. v

My improvement can be applied to-all kinds of sliding windows and doors. For instance, in the case of an ordinary window, the frictioneroller's would be so arranged as te bear against the` inside stop, in order to keep the lower sash pressed against the parting-strip# whilst with the ilpper sash it would bevwell tou-arrange the said rollers so as to bear against'the outside stop, and thus press that sash up against `the parting-strip. There would consequently be a. perfectly weather4tightjoint all round, andweather-strips could be dispensed `with,

I am well 'aware that many devices have been invent'edfor preventing the sash fromdescendingwhen raised to nny'given point, and to such I lay-no clainri, the object of my invention being an entirely different one.

What I claim as my invention, and desireto secure by Letters Patent, is

The combination, with tho sash and frainefofa sliding window or door, of a` combined spring, A, and roller,

B, arranged und operating substantially as and forthe purposes herein specified.l
